Context: Document 1: Eddie Locke: Eddie Locke was a part of the fertile and vibrant Detroit jazz scene during the 1940s and 1950s, which brought forth many great musicians including the Jones brothers (Hank, Thad, and Elvin), Kenny Burrell, Lucky Thompson, Tommy Flanagan, Barry Harris, and so many others. He eventually formed a variety act with drummer Oliver Jackson called Bop & Locke which played the Apollo Theater. He moved to New York City in 1954, and worked there with Dick Wellstood, Tony Parenti, Red Allen, Willie "The Lion" Smith, and Teddy Wilson amongst others. During this time he came under the tutelage of the great Jo Jones, and eventually became known as a driving and swinging drummer who kept solid time and supported the soloist. During the late 1950s he formed two of his most fruitful musical relationships, one with Roy Eldridge, and the other with Coleman Hawkins. His recording debut came with Eldridge in 1959 on "On The Town". He later became a member of the Coleman Hawkins Quartet in the 1960s along with pianist Tommy Flanagan and bassist Major Holley. That group made many fine records including the exquisite album "Today and Now", in 1963. Throughout the 1970s, he played with Roy Eldridge at Jimmy Ryan's in Manhattan, and wound out his career freelancing, as well as teaching youngsters at the Trevor Day School on Manhattan's upper west side.
Document 2: Detroit: Become Human: The characters Connor and Markus are played by Bryan Dechart and Jesse Williams, respectively. Clancy Brown, Lance Henriksen, and Minka Kelly portray supporting characters Lieutenant Hank Anderson, Carl Manfred, and North, respectively. There are three different composers, one for each playable character: Philip Sheppard for Kara, Nima Fakhrara for Connor, and John Paesano for Markus. Sheppard's cello sequence in Kara's theme was inspired by the flames of a log fire, whereas the motif layered over it came from the two syllables in her name. Fakhrara created custom instruments and used vintage synthesizers in order that the sound could represent the robotic nature of Connor. Paesano's music was made with the idea that it would be ``like a church hymn '', personifying Markus' transformation into a leader. Sheppard recorded at Abbey Road Studios with the English Session Orchestra; Paesano was at Synchron Stage Vienna with the Synchron Stage Orchestra. Director of photography Aymeric Montouchet used`` thick grain and shaky long lens'' with shallow depth of field for Kara, ``small, tight grain ''and a blue palette for Connor, and orange and white colours for Markus. The game was released to manufacturing on 23 April 2018, after four years of production.
